LOAD BAR Filed Jan. 8, 1930 lnverzfofi Patented Nov. 24, 1931 UNITED STATES PATENT OFFICE -EDWI N BEREIT, OF MENTOR, OHIO, ASSIGNOR TO THE CLEVELAND CRANE & ENGINEERING COMPANY, OF WICKLIFFE, OHIO, A CORPORATION OF OHIO LOAD BAR Application filed. January 8, 1930. Serial No. 419,422.

This invention relates to suspended carriers of the monorail type, and more particularly to a load bar for such carriers.

An object of this invention is to provide an improved form of load bar for traveling carriers.

Another object of this int ention is to provide a form of carrier load bar which can be cheaply manufactured from commercial in rolled stock.

The invention may be further briefly summarized as consisting in certain novel combinations and arrangements of parts hereinafter described and particularly set out in the appended claims.

In the accompanying sheet of drawings,

Figure 1 is a side elevational View showing the outline of a suspended carrier embodying the load bar of my invention.

Figure 2 is a top plan view of the bar.

Figure 8 is an end elevation of a suspended carrier with parts thereof broken away showing the load bar in assembled relation, and

Figure 4 is a side elevational view of a bar of stock used in constructing my load bar.

In the drawings illustrating my invention, I have shown my load bar embodied in a suspended carrier of the monorail type, but it will be understood, of course, that the load bar of my invention may be embodied in carriers of various types. Load bars, as heretofore used in carriers of this kind, have generally been constructed in the form of castings, and because of the many defects which castings are inherently subject to, load bars of that form of construction are unreliable and are frequently broken during service of the carriers.

' I have found that more reliable and more durable carrier load bars of this type, can be more cheaply manufactured from bars of commercial rolled stock, and in the drawings I have shown a load bar of this type of construction embodied in a suspended carrier.

This carrier comprises heads 10 and 11 suspended from a monorail 12, and a substantially horizontal load bar 13 pivotally con nected adjacent its ends to the heads. The carriers heads may be constructed according to any suitable design, but as illustrated in the drawings, each head is made in the form of a U-shaped yoke 14, having wheel mounting bearing members 15 secured to the ends thereof. By means of these bearing members each yoke is suspended from a pair of wheels 16, adapted to travel along the laterally extending flanges 17 of the rail 12. The yokes are each provided with a strut 18, which e21- tends between and is secured to the legs of the yoke in spaced relation to the intermediate straight portion 19 of the yoke.

The load bar, according to my invention, is preferably made up of two sections 20 and 21 of commercial rolled stock, such as steel channel-shaped bars, which are readily available I I in all desired sizes. These sections are arranged back to back as shown in Figure 2, in spaced, substantially parallel relation. To reduce the depth of the end portions of the load bar, I cut out web portions adjacent the ends of each of the sections of rolled stock, as clearly shown in Figure a. The openings thus formed in the webs of the sections are then closed by bending the flanges toward each other to bring the cut edges 22 of the web into meeting relation along the lines 23,

as indicated in Figures 1 and 3. After the Web portions have thus been cut out and closed, the meeting edges of the web may be Welded together if desired along the lines 23.

For supporting the load bar I provide bearing members mounted upon the reduced end portions of the sections. These bearing members are preferably secured in place by being welded to the top and bottom flanges of both sections. These members may be constructed of any suitable shape but, as here illustrated, are shown circular in form, and are arranged with their central openings 25 in aligned vertical relation with each other, and with the space 26 between the backs of the sections. Vhile any suitable means may be employed for rigidly connecting the sections together, the bearing members when welded to the flanges of the sections also accomplish this purpose.

Bumpers 27 may be secured at the ends of the load bar if desired. These bumpers may be constructed in any suitable form, and when secured to the ends of the sections, as by weldsections. This member, alsoassists in hold;- mg the sectionsl' 'together, b'utGits prineipal function is to form a suitable mounting for I attaching the load which the carrier isto sup ort:-

as shown in Figure 3 of the drawings, the re;

duced end portions of the bar are received between the struts and the intermediatestraight portions of the yokes. At'each end" otgthebar the top;bearingmember-QQ engages thelower flat surfaceot the -str'ut f 18-; while the lower bearingmember: 24 engages tli-enp per flat su-rtaceof the intermediate straight?

The ends of the load banare thus pivotally and: detachably connected to-the respective carrier head's.

It will now be readily understood that I have? rovideda stron andreliable form of; load-bar, wh chfcanbe cheaply construe-tech from bars-of commercial rolled, stock. Load bars, constructed in this manner according to my' nvent on, are very rugged, and are not likely tofail in servlce'. i V
